70 k20 3/4 ton build "Shirley" - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Howdy from Texas ya'll

I have been a member of this forum for some time now, I have a 68 c10 that I'm slowly, but surely restoring.

I recently (Feb 2016') had the pleasure of buying a 1970 Chevrolet K20 3/4 ton 4x4, with a hydraulic flatbed from a coworker. The truck was purchased with a tired out 350 motor that had leaks from every possible seam. The truck was not drivable when he sold it to me, but I took a leap of faith and bought it anyway.

I proceeded to have to truck taken to a small hot rod shop in the city that I work in called Freer, Texas. There the truck was to undergo a heart transplant as well as other minor things here and there to get here road worthy.

I decided to name her Shirley.

This is her with some jeep wheels and 37" tires that the previous owner tried pulling off, looked cool, but rubbed too much and motor and trans didn't move them well enough, clutch was toast and flywheel was all heat spotted.

Here is how she looked when I got her, and a pic of her build sheet.

Congrats, thats a very cool rig. But I have to ask what are "jeep" wheels?

Nice truck and lift bed! gonna be a whole lot nicer with a rebuild and new clutch!

7dee2 · 07-09-2016, 09:52 AM

Ha, the small block had some nice crud going on reminds me of my blue c30!

A 454 just made Shirley even peachier she's a burly girl!

stevenbear72 · 08-27-2016, 03:03 PM

Apologies for not updating sooner, been swamped with working night shift, I'm back to working day shift and no longer being a zombie.

With that being said, here are some more parts that I've gathered for my build.

Soaked the Comp lifters for a few days while we worked on other things for the build

Ordered some nice longtube Hedman hedders, which will be heat wrapped later

New Duralast waterpump

Preppin' to install pistons and rods

Comp Cams Thumper cam that's going into motor

stevenbear72 · 09-06-2016, 12:52 PM

Forgot to add the photo of the Mellings high volume oil pump.

Cam going in

Here you can see the dual springs and new valve seals that were added to the heads

Prepping the motor for paint

Here she is freshly painted.

My buddy decided to paint the intake Silver and add a clear coat to the Edelbrock intake. The carb ill be running is a 650 dual feed Holley that I had laying around. Fresh carb rebuild on it as well.

stevenbear72 · 09-06-2016, 01:21 PM

Received some more goodies for Shirley. New flywheel, pressure plate, & clutch.

New cap and rotor

New high volume Delphi fuel pump, buddy said he orders it from a 69 Impala with the 427 at parts store.

New tach

Fan relay kit

hedder wrap

New duralast motor mounts

New spark plug wiring set

New gauges

New starter

stevenbear72 · 09-06-2016, 01:38 PM

New Optima battery, these things are freaking expensive!

New Champion 3 row radiator

7dee2 · 09-13-2016, 09:57 AM

Nice parts, can't wait to hear it run!

swamp rat · 09-23-2016, 10:19 PM

Lots of goodies and coming together nicely!

**Dieselwrencher** · 10-06-2016, 07:47 PM

Man, Shirley is a real nice and clean K20. That dump bed is a nice treat too. Nice work on that 454. Do those headers fit a 2wd car or are they for a BBC in a 67-72 4wd?

I used this radiator on my sons truck. if it has the aluminum fan shroud with the 2 electric fan option, make sure the fan shroud does NOT touch the fins of the radiator. On mine it barely touched one tube and wore a hole in it after some time and I had to disassemble and weld it up. What a pain in the arse. On the Hulk Build I made sure to trim it!

Good looking build!

**Yukon Jack** · 12-01-2016, 04:38 PM

ryanroo · 12-03-2016, 11:50 AM
